` The Schedule` `referred to these Letters' Patent and mkingpatt of: the Bama. y

Be it known that I, Vif-ALDO P. CRAIG, of' Milton, Trimble county, Kentucky, have invented a new and l nsei'ul- Mode of Constructing Dams, Breakwaters,

Levees, &c.; and I hereby declare the followingto be a, full, clear, and exact description thereof', reference being `had tothe accompanying drawings, making part of this specification. y My invention `relatesfto a mode of constructing dams, breakwaters, levees, and the like, by which I am enabled tocressji-ny body -of' water wherein`- piles can be driven, the structure when complete being proof against the inroads .of water-rats and other burrowing i animals, and against the undermining action of the water.'

Figure 1 is a 'side eleyation, and i Figure `2, a top view, partially in section, of ara-nge ci' guide and sheelt-piling,.on `my plan.

`Figure 3 is a transverse `section thereof, embedded in a leveeor river-wall. c p

Figure 4 shows one ofmy sheet-piles detached.

lfigure shows a series' of guide-piles, connected with swinging sections. y

Figure 6. is a topviewthereof."` e

shownin gs. 1, 2,'V and 3. 4 The inner `tiers of guide-piles A, being rst driven,

.My mode of construction for a simple levee-wall is have longitudinal timbers or walings B, spiked to them, which walings afford guides for driving a tier of 1 sheet-piling, O,\vl1'ose edges are alternately V-tongued .and grooved, and Whichare bevelled at their lower ends, as shown, so as to enable them to be guided to their placesyin the `act of driving, and thus to forma continuous wall of partition, impervious both to water and animals.

a river orl harbor, I provide balksl or walings Gr,to` whose lower sides are secured piles H, and which are hinged te the main walings by bolts or pintles I. A section of this construction being brought down tothe position represented atX, affords a guide formdriving two lines' offsheet-pilings, C', on the lip-stream side of the balks, and which, being iilled'in with rubble or con` crete'J, ai'ords a permanent pienor causeway.

lThis section, then, may form the abutment for the l next, which being finished inlike manner, may be followed by another section, and so on indefinitely.

I claim herein as new, and of my invention-1 1. rlhe combined arrangement of guidepiles A A, walings B'B, and sheet-piling C, substantially as here, in described, the sheet-piling being flanked on either side'by the `guide-piles and walin gs, and all constructed and' applied substantially in the manner and forjthe, j purposes set forth.

2. .The piles H, attached to the lower side of hinged or jointed sections Gr, so as to be drivenl in the act of lowering saidjsectionsas and for the purpose specified.'

3'. The combination, with the subject of the last precedingclaus'e', of the sheet-piling 0', and concrete or rubble-fillingJ, asandfor thepurpcse set forth;

In testimony of which invention, I hereunto set my hand. l f VW..1".. CRAIG.
